Cisco Call Management Record Field Descriptions

CMR Field
Descriptions

The
following table contains the fields, range of values, and field descriptions of
the CMRs in the order in which they appear in the CMR.

Table 1 CMR Field
Descriptions

Field Name

Range of Values

Description

cdrRecordType

0,
1, or 2

This field specifies the type of this specific record. The
following valid values apply:

0—Start call detail record
(not used)

1—End call detail record

2—CMR record

Default - For CMRs, this field always specifies 2.

globalCallID_callManagerId

Positive Integer

This field specifies a unique
Cisco Unified Communications
Manager identity.

This field makes up half of the Global Call ID. The Global Call
ID comprises the following fields:

globalCallId_callId

globalCallID_callManagerID

All
records that are associated with a standard call have the same Global Call ID
in them.

Default - Ensure this field always is populated.

globalCallId_callId

Positive Integer

This field specifies a unique call identity value that gets
assigned to each call. The system allocates this identifier independently on
each call server. Values get chosen sequentially when a call begins. Each call,
successful or unsuccessful, receives value assignment.

This field makes up half the Global Call ID. The Global Call ID
comprises the following two fields:

globalCallId_callId

globalCallID_callManagerID

All
records that are associated with a standard call have the same Global Call ID
in them.

Default - Ensure this field always is populated.

nodeId

Positive Integer

This field specifies the server, or node within the
Cisco Unified Communications
Manager cluster, where this record gets generated.

Default - Ensure this field always is populated.

directoryNumber

Integer

This field specifies the directory number of the device from
which these diagnostics are collected.

Default - Ensure this field always is populated.

callIdentifier

Positive Integer

This field identifies the call leg to which this record
pertains.

Default - Ensure this field always is populated.

dateTimeStamp

Integer

This field represents the approximate time that the device goes
on hook.
Cisco Unified Communications
Manager records the time when the phone responds to a request for
diagnostic information.

Default - Ensure this field always is populated.

numberPacketsSent

Integer

This field designates the total number of Routing Table Protocol
(RTP) data packets that the device transmits since starting transmission on
this connection. The value remains zero if the connection is set to
"receive
only" mode.

Default - 0

numberOctetsSent

Integer

This field specifies the total number of payload octets (that
is, not including header or padding) that the device transmits in RTP data
packets since starting transmission on this connection. The value remains zero
if the connection is set to
"receive
only" mode.

Default - 0

numberPacketsReceived

Integer

This field specifies the total number of RTP data packets that
the device has received since starting reception on this connection. The count
includes packets that are received from different sources if this is a
multicast call. The value remains zero if the connection is set in
"send
only" mode.

Default - 0

numberOctetsReceived

Integer

This field specifies the total number of payload octets (that
is, not including header or padding) that the device has received in RTP data
packets since starting reception on this connection. The count includes packets
that are received from different sources if this is a multicast call. The value
remains zero if the connection is set in
"send
only" mode.

Default - 0

numberPacketsLost

Integer

This field designates the total number of RTP data packets that
have been lost since the beginning of reception. This number designates the
number of packets that were expected, less the number of packets that were
actually received, where the number of packets that were received includes any
that are late or duplicates. Thus, packets that arrive late do not get counted
as lost, and the loss may be negative if duplicate packets exist. The number of
packets that are expected designates the extended last sequence number that was
received, as defined next, less the initial sequence number that was received.
The value remains zero if the connection was set in
"send
only" mode. For detailed information, see RFC 1889.

Default - 0

jitter

Integer

This field provides an estimate of the statistical variance of
the RTP data packet interarrival time, measured in milliseconds and expressed
as an unsigned integer. The interarrival jitter J specifies the mean deviation
(smoothed absolute value) of the difference D in packet spacing at the
receiver, compared to the sender for a pair of packets. RFC 1889 contains
detailed computation algorithms. The value remains zero if the connection was
set in
"send
only" mode.

Default - 0

latency

Integer

This field designates value that is an estimate of the network
latency, expressed in milliseconds. This value represents the average value of
the difference between the NTP timestamp that the RTP Control Protocol (RTCP)
messages indicates and the NTP timestamp of the receivers, measured when these
messages are received.
Cisco Unified
Communications Manager obtains the average by summing all estimates
then dividing by the number of RTCP messages that have been received. For
detailed information, see RFC 1889.

Default - 0

Note

CMR
records will not show latency for all phone loads. For example, for SIP 9.2.1
and 9.2.2, the latency will not show, as it has not been implemented in these
loads.

pkid

Text String

This field identifies a text string that the database uses
internally to uniquely identify each row. This text string provides no meaning
to the call itself.

Default - The system always populates this field with a unique
ID.

directoryNumberPartition

Text String

This field identifies the partition of the directory number.

Default - Empty string,
"". This field may
remain empty if no partition exists.

globalCallId_ClusterId

Text String

This field designates a unique ID that identifies a single
Cisco Unified
Communications Manager, or a cluster of
Cisco Unified
Communications Managers.

The system generates this field during installation, but
Cisco Unified
Communications Manager does not use it: globalCallId_ClusterId +
globalCallId_callManagerId + globalCallId_callId.

Default - Ensure this field always is populated.

deviceName

Text String

This field identifies the name of the device.

Default - Empty string
"". This field may
remain empty if no device name exists.

varVQMetrics

Text String

This field contains a variable number of voice quality metrics.
This field comprises a string of voice quality metrics that are separated by a
semicolon.
